Abstract
A jet pump assembly is adapted to be releasably attached to a tubular member of a tubular string in an oil well. The jet pump may be pumped out of the tubular string to the surface by a reverse flow of power fluid down the well between the tubular string and the casing of the well. Consequently the jet pump may be serviced or reconfigured to a direct pumping mode without the necessity of a wire line or other apparatus. A sensor for measuring downhole parameters such as temperature and pressure etc. is positioned within a cavity located in a lower portion of the jet pump so as to be removable from the well with the pump.
